Answer:
Refraction is the bending of light (it also happens with sound, water and other waves) as it passes from one transparent substance into another.

Answer:
Refraction happens because the speed of the wave changes. Light travels slower (compared to its speed in air) in a more dense material like glass. The wavelength will also decrease in order to keep the frequency constant.
